RR is promoting made in india concept with obviously an indian in this video.F125IN says it has auto start ,where as RR has manual start,its weight is highter by 500 pounds. F125IN talks about FADEC,but no such thing from RR.Its a tough choice. RR is in touch wiht HAL for almost two decades. where as US end user restrictions,availability of spares,transfer of tech all questionable issues. may the best product win the contest!

F125 is basically a commercial jet plane engine made to fit Fighter Jets. Looking at the specs the things like mileage, weight auto start and FADEC would have made a difference if the jet can accelerate as good as a Fighter Jet Engine, thats where the problem is. Taiwan has brought some of these and they have reported the same problem. Do we want a Jet Figheter to move like a commercial plane???

The plane's movement is affected by its aerodynamics and mass, the engine is not going to change that. What the RR engine does change is spool up time to max thrust, but this is a character of all high(er) bypass turbofans.

It is not as if we are using a Trent or a GE90 which take upto 5-7 seconds to spool up. A two second spool up is not so bad when you consider the improvement a modern, high-bypass engine brings to the platform.

Just how many times do the pilots go from forward idle to TOGA, or vice versa? I'll tell you, only once, when taking off. No one drastically reduces the thrust once in air since losing energy in air combat is as good as committing suicide.

"its amazing how pathetic idiots keep trying to find faults where there are none."

They said "watched by a Indian official". Does it mean government official? Hell no! Some Indian subcontractor who plans to get a cut out of the deal watched it. Why would an Indian government official be part of commercial that is sponsored by 'one' of the bidders for the project? Wouldn't Honeywell be outraged?

Does that go down your pathetic gullible head, or whatever is left of it?

"The Mk 821 engine was installed into a Royal Air Force Jaguar for the ground test at Cosford, which was witnessed by a representative of the Indian Government."

do you understand what a representative of the Indian Government means you dimwit ? RR isn't going to "hire" some Indian dude to act as if its a movie..the event where the Jaguar was tested with the Adour Mk 821 to full reheat was filmed and the small presentation was made, which will be shown to important people in the GoI, HAL and IAF. now go back to your school books and study harder, you retard.
